You and your landlord can agree to modify the terms of the lease, including changing the due date, but they cannot do so unilaterally, and they cannot double-charge you rent. You should be paying for a month at a time, regardless of when you actually tender payment. Thus, there should be a way to pro-rate the change so it works out for everyone, wherein you pay the same total amount overall and in the process you might actually save yourself some funds by having five or six extra days to submit payment that first month. But you should NOT pay a full rental month on the 25th and then another full rental month that next first.
